It is definately normal behaviour on my Amstrad (CPC6128) -- but
only the B drive. This has something to do with the minimal decoding
internally in the machine (I never bothered to trace it down in the
circuit diagram).
 
I would say that in most computers it is safe to remove the disk
when the little light is on, so long as you are _sure_ it is not being
accessed (and, obviously, that there are no open files on it --
especially for writing).  I usually listen to the motors (I have
5.25" drives) to tell when the disks are no longer needed (and of
course keeping an eye on the program that is working).

Of course, there are a few occasions when you want to remove the
disk while it is being accessed..... :-)  [Yet another comment about
computers which follow instructions too literally!]
